@ Sam - I am having the same issue.. :(

@ Manisha

q3--> a1.a2..an=1 so all ai = 1
so the function is 2^n

q4) nC0 (1-p)^n = nC1 . p. (1-p)^(n-1)
=> 1-p = np(1-p)

solve this and u get ans (b)

Can somebody please please explain how to go about 24, 16, 28 and 9 ( I do not understand the explanation given in the post previously for 28 and 9 .. what is the logic for solving?)
